Fun game! Trying to figure out the puzzles is fun. I busted out my notes app to start figuring out the patterns. maybe a QOL feature could be something that helps you keep track of the patterns you tried so that they can stay in the game.
Hmmm, that's an interesting idea... something like a "breadcrumb" that shows the last valid blocks, right? I like it. I've included it in the backlog, as I plan to resume development on the post-jam versions next week.
